A force of 9.0N is applied to a body at rest on a smooth horizontal surface.
If the body has a mass of 18.0kg and it moves in the direction of the force, find the work done in.
a. The first four second. b. The fourth second ?

What is the acceleration?

How far does it move in the first four seconds? How far does it move during the fourth second?

What is the relationship between the force on an object and it's displacement in the direction of that force and the work done on it?
